It supplies the body with essential supplies to the cells & removes waste from cells. respiratory system circulatory system

Vocabulary Review Quiz The heart is the main organ of this system. It supplies the body with essential supplies to the cells & removes waste from cells. Circulatory system Muscular System Respiratory system Skeletal System A system that consists of organs that supply the body with a constant supply of oxygen and gets rid of carbon dioxide. The main opening through which the air enters the lungs. trachea bronchi alveoli diaphram Veins, capillaries, & arteries are examples of what? blood vessels muscles joints connective tissue

Vocab Review Quiz, cont…. The exchange of gases between your body and the air is? Ashthma AQI Alveoli Respiration A dome-shaped muscle that separates the lungs from the abdomen. gastrocnemius abdominals latissimus dorsi diaphram Tiny air sacs in the lungs where carbon dioxide is exchanged with oxygen. arteries bronchi alveoli trachea

Blood Vessel Review Quiz Carries blood AWAY from the heart to the body Veins Arteries Capillaries Carries blood from body TO the heart A type of blood vessel that connects the arteries to the veins The top chambers of the heart are called? Ventricles Atrium Septum valves The bottom chambers of the heart are called? Valves

“Its Time to Deliver” List the TWO main jobs of the Circulatory System. Carries Food, water & Oxygen to all the cells Removes waste from the cells

Circulatory System What body parts make up the circulatory system? Heart Blood Blood vessels –(3 TYPES) Veins Carries blood TO the Heart Arteries Carries blood AWAY from the Heart Capillaries Tiniest blood vessels in the body Exchanges oxygen & nutrients and removes waste from the cells What is the hearts main job? Transport blood (food, water, & oxygen) to all parts of body and removes waste from all the cells

A mixture of solids in a large amount of liquid called plasma Concept Mapping 16-3 Blood: A mixture of solids in a large amount of liquid called plasma Platelets White Blood Cells Red Blood Cells Plasma Blood Vessels: Purpose: to transport blood throughout the body Arteries Veins capillaries Blood Types: A B AB O

Blood Four blood types (What type are YOU?) What is blood made up of? Type B Type AB Type O What is blood made up of? Plasma Liquid part of blood (92% Water) Platelets Help blood clot at the site of a wound Red blood cells Carries Oxygen too cells and Carbon Dioxide away from cells White blood cells Carry germ fighters from immune system to areas of the body that need them

Blood Flow Paragraph Blood enters the heart from the upper and lower BODY. This blood is rich in CARBON DIOXIDE. This flows from the RIGHT ATRIUM to the RIGHT VENTRICLE. From the right ventricle, blood is pumped to the LUNGS through the pulmonary artery. This blood rich in oxygen returns to the HEART through the pulmonary vein. It then travels to the LEFT ATRIUM into the LEFT VENTRICLE. The oxygen rich blood leaves the heart from the left ventricle through the AORTA. The aorta is the LARGEST artery in the body that branches into smaller arteries. Blood flows through these smaller arteries. Oxygen, nutrients and waste products are exchanged at the CAPILLARIES. The capillaries are the tiniest blood vessels in the body. Carbon Dioxide from the cells is then transferred into the VEINS and back to the heart.

Vocabulary Review Quiz A system that consists of organs that supply the body with a constant supply of oxygen and gets rid of carbon dioxide. Circulatory system Muscular System Respiratory system Skeletal System The main opening through which the air enters the lungs. Trachea Bronchi Alveoli diaphram

What does the respiratory system do? Supplies the body with constant oxygen and gets rid of carbon dioxide

Two types of respiration External—exchange of oxygen & carbon dioxide between the blood and the air in the lungs Internal—exchange of gases between the blood and the cells in your body

Respiratory System A person inhales through their Nose & Mouth Trachea is known as the windpipe The Epiglottis prevents food and liquid from entering the trachea. After oxygen travels through the trachea is goes to the bronchi. The bronchi are located inside the lungs of a person The oxygen travels through the bronchial tubes and the oxygen is absorbed by the alveoli, air sacs in the lungs. Oxygen enter these air sacs and is sent to the blood, which delivers the oxygen to the rest of the body. Carbon Dioxide leaves the body through the alveoli and it is exhaled through the lungs. A common problem with the respiratory system is Asthma , a serious condition that causes the bronchial tubes to become narrowed or blocked.

Problems with Circulatory & Respiratory System Hypertension (High Blood Pressure) Can lead to kidney failure, heart attack or stroke Heart Attack Blockage of blood flow to heart Stroke Blood clot in vessels of brain Arteriosclerosis (Hardening of arteries) Reduces that amount of blood that can flow through Asthma Tiny passages in lunch become narrow or blocked Chronic obstructive pulmonary disease (COPD) Chronic lung disease—may need to be on oxygen
