Circulaltory Flashcards
5 functions of the circulatory system:
- Circulate blood throughout the entire body
- Transport of oxygen to cells
- Transport of CO2 away from cells
- Movement of immune system components
- Transport of endocrine gland secretions
Types of Circulatory System
- Open circulatory system
- Close circulatory system
Types of Circulatory System
Blood flows freely through cavities since there are no vessels to conduct blood
Open Circulatory System
Types of Circulatory System
The blood flows through the arteries and veins connected together by capillary
Closed Circulatory System
CIRCULATORY SYSTEM OF ANIMALS
Organisms which have a two-cell layer covering, get their supply of gases and excrete wastes through DIFFUSION.
Simple Organism
CIRCULATORY SYSTEM OF ANIMALS
Division of Circulatory System (2)
- Pulmonary Circulation
- Systemic Circulation
CIRCULATORY SYSTEM OF ANIMALS
- blood is distributed to the tissues and other systems of body.
Systemic Circulation
CIRCULATORY SYSTEM OF ANIMALS
Division of Circulatory System
- blood flows between the heart and lungs to become oxygenated
Pulmonary Circulation
It works as a pump to move the blood round the body.
Heart
Heart
It has four chambers:
- two atria (upper champers
- two vetricles (lower chambers)
Vein
Vena Cava
- superior
- interior
These are tubes or channels that carry blood throughout our body
Blood Vessels
Three types of blood vessels:
- Artery
- Capillary
- Vein
Three tyoes of blood vessels:
It has the thickest wall of all three,, allowing it to withstand the high pressure created by the heart.
Artery
The blood will flow how many seconds?
20 seconds
Assist exhcange of substance between the blood amd tisues
Capillary
It has the thinnest wall to allow substances such as oxygen and usgars to pass through its wall - into or out of the blood.
Capillary
It is less muscular and stretchy than artery, so blood moves through it with low pressure. It also has a special valve that helps blood to go only one way.
Vein
Carries blood away form the heart
Artery
Carries blood back towards the heart
Vein
It is a special fluid primarily contained within the blood vessels.
Blood
4 Main components of blood:
- Red Blood Cells
- White Blood Cells
- Platelets
- Plasma
4 Main components of blood
- carry oxygen, nutrients, and waste
Red blood cells
Main components of blood
- fight diseases and protect the body from infection
White blood cells
Main components of blood
- gather at the site of injury and help th clotting process
Platelets
Main components of blood
- straw-colored liquid where the oher components float in
Plasma
How does our blood get filtered?
Blood gets filtered inside the blood capillaries found in the (1)_____. Useful substances will be absorbed back by the (2)_____ while wastes will be removed in the form of (3)_____,
(1) kidneys
(2) blood
(3) urine
It transports water and nutrients from the roots and the different parts of the plant.
Vascular System
Vascular System for Plants
The vascular system transports _____ and _____ from the roots and the different parts of the plant.
WATER and NUTRIENTS
Vascular System for Plants
Carries water and minerals upward from the roots to different parts of the body.
Xylem
Vascular System for Plants
Move water and nutrients throughout the different parts of the plant.
Phloem
Prevent backflow of certain substancs
Perforations
