Homework Review

1.What is the circulatory system? 2.Functions of the circulatory System 3.Parts of the circulatory system What do I need to learn today?

Today’s Goal  I will know the parts and function of the circulatory system.

The Circulatory System !!!!!

 vie.html?tracking=81347_A

What is it? The organ system that circulates blood throughout the body What does circulate mean? To move or flow in a circle

Functions of The Circulatory System 1.Blood Cells carry energy/glucose (from food person eats) and Oxygen (that person breathes in) to cells all over the body 2. Blood takes Carbon Dioxide and other waste out of cells

We all know that oxygen is the key to living. It's in the air you breathe, in your lungs and in your blood. What you might not know is how oxygen gets into your blood and how the blood carries oxygen through your body.breatheyour body.

How does the oxygen get in the blood?  You breathe air in through your nose and mouth. It then makes its way into your lungs. Oxygen then sticks to red blood cells as they pass through the lungs on their path throughout the body - now the oxygen is in the blood.

How does energy/glucose from food get into you blood? Glucose: is the main sugar found in blood, taken from the food we eat. Once almost fully digested, food moves through the intestines, the nutrients are absorbed through the walls of the intestines and put into the blood.

3 Parts of Circulatory System 1. Heart 2.Blood vessels 3. Blood

3 Parts of Circulatory System 1.The heart pumps the blood. 2.The blood vessels are tubes that carry blood. 3.The blood carries oxygen & nutrients to body cells.

HEART: Muscular organ that pumps blood all around the body. c.com/templatedata/im ports/HTML/CRM/heart/ interact_6.html Parts of the Circulatory System

The Heart The heart has 4 chambers (sections)

Blood with oxygen in it is shown as red Blood without oxygen is shown as blue Red = blood with oxygen in it Blue= blood without oxygen

Exit 1.Which of the following is not a function of the circulatory system? A.Take oxygen to cells B.Remove carbon dioxide from cells C.Take energy to cells D.Take water to cells 2. Name the 1 of the 3 parts of the circulatory system

Thursday Warm Up Put homework on desk 1.What are the 2 functions of the circulatory system? 2.What are the 4 chambers of the heart called?

2 main functions 1.Carry energy/nutrients and oxygen to cells all over the body 2.Remove carbon dioxide and other waste from cells

2. The 4 chambers of the heart Right atriumLeft Atrium Right VentricleLeft Ventricle

Today’s Goal  I will understand the path blood takes through the heart and lungs.

Vocabulary Words  You will use this sheet several days in a row  We will not complete the entire thing today – DO NOT LOOSE IT!

Heart: the main organ of the circulatory system; pumps blood Atrium: the top part of the heart; receives blood Ventricle: the bottom part of the heart; Pumps blood out of the heart Left side of heart: gets oxygen rich blood from lungs Right side of heart: gets oxygen poor blood from body Valve: part of the heart that prevents blood from moving backward

Remember Functions of Circulatory System? Blood carries Oxygen to parts of the body The lungs work with the heart to do this *Because of this the blood flowing through the heart has a very specific “path”

4 Chambers Layout Atrium = the top of the heart Ventricle = the bottom of the heart Memory Tool A = “top” of the alphabet… and top of heart V = “bottom” of the alphabet… and bottom of heart

Blood Flow Visual ata/imports/HTML/CRM/heart/interact_5.ht ml

Blood Flow Steps Step 1. Blood returns to your heart from your body and lungs Oxygen-poor blood from your body flows into your right atrium. At the same time, oxygen-rich blood from your lungs flows into your left atrium.

Step 2. Blood flows from the upper to the lower chambers. –Blood flows from your right atrium into your right ventricle. –At the same time, blood flows from your left atrium into your left ventricle.

Step 3. Blood is pumped back out to your lungs and body. –Your right ventricle pumps blood out of your heart to your lungs, where the blood's oxygen supply is replenished. –At the same time, your left ventricle pumps blood — once again full of oxygen — out of your heart to your body. To lungs For oxygen To body

Thursday  0s-1MC1hcE

Thursday Exit 1.What is the top of the heart called? 2.What is the bottom of the heart called? 3.Where does the heart send blood that is oxygen poor? 4.Once in the right atrium, where does the blood go next?

Friday Warm Up -Put HW on desk -Read Blood Vessels by Jennifer Kenny and answer questions

Exit Ticket Review 1.What is the top of the heart called? Answer = Atrium 2. What is the bottom of the heart called? Answer = Ventricle 3. Where does the heart send blood that is oxygen poor? Answer = to the lungs 4. Where does blood go after the right atrium? Answer = Right Ventricle

Homework  12 min to finish HW and not get a zero  If you did finish > finish poster from yesterday

Today’s Goal 1.I will better understand the path blood takes throughout the body and parts of the heart 2.I will learn the 3 types of blood vessels and their roles in transporting blood.

Revisiting the Path Blood Takes

3 parts of Circulatory System  Heart  Blood Vessels  Blood

Blood Vessels Vocabulary Blood Vessel – tubes that carry blood. 3 kinds = artery, vein, capillary Artery – the blood vessel that carries oxygen rich blood AWAY from the heart (red)

Vein – the blood vessel that carries oxygen poor blood TOWARD the heart (blue)

Artery = blood AWAY from heart (red) Vein = blood TOWARD heart (blue)

Capillary – tiny blood vessels that connect arteries and veins

Aorta Aorta – the biggest artery, connected to the top of the heart

Agenda Blood Vessel Map Blood Vessels Worksheet Artery, Vein and Capillary Venn Diagram

Blood Vessel Map Directions 68B Veins = Blue arrows going towards the heart Artery = red arrows going AWAY from the heart You need a key on the paper – tell people who look at it what they are seeing!

Exit Ticket 1.What type of blood vessels carry blood away from the heart? 2.What color are the blood vessels that carry blood to the heart? 3.What is the largest artery in the body called?

BLOOD VESSELS: Blood travels through your body in hollow tubes called blood vessels. There are 3 types of blood vessels: arteries, veins, capillaries Parts of the Circulatory System

1.One function of the circulatory system is to carry ENERGY and OXYGEN to cells in your body.

2. ARTERIES are the blood vessels that carry blood away from the heart.

Review  Blood Vessels ARTERIES take blood away from the heart. VEINS take blood to the heart.

Review  Blood Vessels CAPILLARIES connect Arteries and Veins

Parts of Blood Blood may seem like just one thing, but it is really made of four main parts

Hemoglobin: part of red blood cells Red Blood Cells: (RBC) part of blood that carries oxygen and carbon dioxide. (Make blood red)

White Blood Cells: Part of the blood that fights infection

Plasma: yellowish liquid part of blood that holds the other parts of blood together (think cytoplasm)

Platelets: Part of the blood that causes clotting (scabs) Oxygen: picked up in the lungs by blood, in red blood cells Carbon Dioxide: released by red blood cells in the lungs
