30.4 Blood Vessels and Transport Arteries, veins, and capillaries transport blood to all parts of the body.

Aim: What are the human transport vessels? I. Human Transport Vessels A. Humans have a closed transport system B. Transport Vessels 1. Arteries a. Thick,

Circulatory System. Functions: Carries oxygen and nutrients to organs and tissues Carries oxygen and nutrients to organs and tissues Transports away carbon.

The Circulatory System. Function  Consists of the heart and blood vessels  Carries oxygen and nutrients to the body’s cells and remove carbon dioxide.

The Circulatory System. 3 Main Functions 1. Transport Oxygen from lungs 2. Transport Carbon Dioxide to lungs 3. Carry nutrients to body.

Cardiovascular System Chapter 16.1 This is a collection of organs that transport blood throughout the body.

Blood Vessels. Learning Objectives: Compare and understand the difference in the structure and function of Arteries Veins Capillaries.

CARDIOVASCULAR SYS A collection of organs that transport blood throughout the body. The human body has systems that transport gases, nutrients, and wastes.

THE CIRCULATORY SYSTEM

These are tiny pieces of cell which have no nucleus. Platelets Clump together when blood vessels are damaged and help to clog a ‘meshwork’ of fibres which.

The Structure of the Cardiovascular System General introduction.

Blood Vessels Arteries, veins, and capillaries. Arteries Take blood away from the heart Have thick walls Usually carry oxygen-rich blood – Exception:

CARDIOVASCULAR SYSTEM Ms. Kelly 7 th Grade Health.

Circulatory/ Cardiovascular System. Circulatory System (aka: Cardiovascular System) Function: Carries needed substances to cells and carries wastes away.

THE CIRCULATORY SYSTEM transports oxygen and nutrients throughout the body carries away wastes made up of blood, the heart, and blood vessels.

The Circulatory System. The Bloodmobile Jobs of the Circulatory System: Transport gases, nutrients, and waste to and from all your cells Help fight disease.

Blood and circulation

What is blood for? red cell white cells platelets plasma Appearance Function

What is blood for? red cell white cells platelets plasma Appearance Function Carry oxygen Fight disease Clot blood and stop bleeding Carry dissolved gases and nutrients

Listening to your blood What are you hearing?

Checking blood is still moving

Different blood vessels Arteries Capillaries Veins Carry Blood Pressure Walls are Blood is Pulse

Different blood vessels Arteries Capillaries Veins Carry Blood Away from the heart From arteries to veins Towards the heart Pressure High Low Very low Walls are Thick and muscular with elastic fibres Very thin and leaky, one cell thick Thin Blood is Oxygenated Exchanging gases and nutrients with cells De-oxygenated Pulse strong none None

Where does blood go? Role play

The journey of a blood cell around the body heart lungs body organ muscle oxygen carbon dioxide carry in out red blood cell takes gives out oxygenated blood deoxygenated blood How many times does the blood go through the heart? What is this called?
