Functions of the circulatory system

Carry nutrients (amino acids, glucose, fatty acids and O2) to tissues
*Carry waste products from tissues for disposal (urea, NH3 and CO2)
Distribute compounds throughout the body

What are Elastic Arteries (Large)?

thick walled arteries by the heart and have a high proportion of elastin (aorta and major branches)

What are Muscular Arteries (Distributing) ?

Deliver blood to specific organs ( high proportion of smooth muscle)

What are arterioles?

Smallest arteries with lesser proportions of smooth muscles and elastin

What are Capillaries?

Endothelial Cells that are covered with a basement membrane that functions in the exchange of materials between blood and tissues

Veins carry blood in what direction?

To the heart

What are veins?

Smooth Muscle circularly arranged

Function of the Right Ventricle

recieves blood from the right atrium and transports the blood to the pumonary arteries

semilunar valves

Valves loacted between the ventricles and arteries; prevents back flow of blood leaving the ventricles

Function of the Aorta

carries blood from the left ventricle to the arteries serving all the parts of the body

What is Pulmonary Circulation

Blood circulates from right ventricle to the lungs and back to the left atrium

What is the Hepatic portal System

(liver) transports blood collected from the absorptive areas of the digestive system to the liver then returned to the heart

Blood Circulation Pattern

1. Superior or Inferior vena cava 2. Right atrium 3. Atrioventricular valve 4. Right ventricle 5. Pulmonary valve 6. Pulmonary artery 7. Capillaries in the lungs 8. Pulmonary veins 9. Left Atrium 10. Mitral Valve 11. Left Ventricle 12. Aortic semilunar valve 13. Aorta 14. Organ 15. Superior or Inferior Vena Cava

( ) is the latin prefix for "heart"?

Cardi

What is the sound the heart makes when the Atrioventricular valve snaps shut?

Lub

What is the largest artery in the body?

aorta

What is the meaning of the prefix "erythro-"?

Red

What is the meaning of the prefix "leuko-"?

White

What are the types of capillaries?

continuous, fenestrated, sinusoids

What are continuous capillaries?

endothelial cells held together by tight junctions (skeletal muscle)

What are fenestrated capillaries?

leaky capillaries with pores that allow for rapid absorption and filtration (kidney and intestines)

What are sinusoidal capillaries?

enothelial cell layer that has numerous larger intercellular gaps and an incomplete basement layer. Allows for exchange of large molecules and materials such as red blood cells (liver, spleen, lymph nodes, bone marrow, endocrine glands)

What are the type of veins?

Veins and Venules

What are venules?

Function in the exchange of materials between blood and the tissues at a large diameter

What are Lymph Ducts?

Ducts in the lymphatic system that secretes a clear, yellowish fluid that is similar to blood, but it has no red blood cells or platelets.

Function of the right atrium

to collect deoxygenate blood from the superior and inferior vena cava and moves to the right ventricle

Function of the Pulmonary Artery

carries deoxygenated blood from the right ventricle to the lungs.

Function of the pulmonary vein

carries oxygenated blood from the lungs to the left atrium

Function of the Left atrium

Receives oxygenated blood from the pulmonary veins and pumps to the left ventricle

Function of the left ventricle

Largest heart chamber. Pumps blood to the aorta from the left atrium

atrioventricular valves

Located between the atrias and ventricles; prevents blood from flowing from the ventricles back into the atrias No valves where the vena cava and pulmonary veins enter the heart

Function of the vena cava

Largest vein in the body; Has two parts (superior and inferior)

Function of the superior vena cava

carries deoxygenated blood from the upper body to the heart

Function of the inferior vena cava

carries deoxygenated blood from the lower body to the heart

Function of the Coronary Arteries

Multiple arteries running on both sides of the heart and supply nutrients and O2 to the heart muscle

What is a Portal system

Blood passing from one organ to another organ that is not the heart; passes through two capillary beds in a series

What is the Hypothalamic_hypophyseal Portal System?

Blood from hypothalamus goes to hypophysis (pituitary) before returning to the heart. Carries hormone's (releasing hormones) from the hypothalamus to the pituitary gland.
