Circulatory System In Hunans

Question 0

Bicarbonate buffering system

Answer 0

• carbon dioxide and water can male carbonic acid or bicarbonate to fox ph levels
• blood is an important part of this bc it carries the crucial ions that make it

Question 1

Transport of gases

Question 2

Transport of nutrients and wastes

Answer 2

Amino acids and simple sugars are absorbed into the bloodstream and transported through the body

Question 3

Adult circulation: cardivascular sustem is made up of

Answer 3

Four chambered heart
Network of blood vessels
Blood

Question 4

Adult circulation

Answer 4

Oxygenated blood goes fron:
Left ventricle to
Aorta
To arteries
To arterioles
To capillaries

Exchange of gases nutrients and waste occurs through the capillaries

Question 5

Capillaries go to…

Answer 5

Venules then
Veins then
Deoxygenated blood goes through inferior and superior vena cava back towards the heart

Blood enters right atrium, right ventricle, pulmonary arteries then to the lungs to pick up oxygen

Oxygenated blood returns to the heart by pulmonary vein to enter left ventricle

Question 6

Fetal circulation

Answer 6

• bipasses the lungs bc it is one of the last things to mature
• uses forman ovale, ductus arteriosus and ductus venosus

Question 7

Foramen ovale

Answer 7

-hole btw the right and left atrium that shunts blood away from the right ventricle

Question 8

Ductus arteriosus

Answer 8

Connection between the aorta and pulmonary artery that prevents any blood in the right ventricle from entering the circulation of the lungs

Question 9

Ductus venosus

Answer 9

Moves oxygenated blood from the umbilical vein to the inferior vena cava of the fetus allowing oxygenated blood to bypass the liver and travel more to the brain

Question 10

The heart

Answer 10

-driving force of the circulatory system
-right Side pumps deoxygenated blood
Into pulmonary circulation
-left side pumps oxygenated blood into systematic circulation

Question 11

Blood vessels

Answer 11

Three main types are
1 arteries
2. Veins
3. Capillaries

Question 12

Arteries

Answer 12

Transport oxygenated blood away from
The heart
-EXCEPT for the pulmonary arteries which transport deoxygenated blood from the heart to the lungs

Question 13

Veins

Answer 13

• take deoxygenated blood towards the heart
• EXCEPT for pulmonary veins which carry oxygenated blood from the veins to the heart

Veins carry into heart

Question 14

Capillaries

Answer 14

Very thin cell wall where things can pass through

Question 15

Lymphatic system

Answer 15

-its vessels transport lymph to the cardiovascular system

Question 16

Blood

Answer 16

• plasma is the liquid portion of blood

- cellular components are erythrocytes leukocytes and platelets

Question 17

Erythrocytes

Answer 17

• red blood cells
• oxygen carrying components of blood
• contains alot of hemoglobin
• disk like shape
• formed in bone marrow

Question 18

When hemoglobin binds oxygen its called

Answer 18

Oxyhemoglobin

Question 19

Leukocytes

Answer 19

• white blood cells
• larger then erythrocytes
• serve protective functions
• mature into macrophages or lymphocytes
• macrophages phagocytize pathogens or activate an immune response
• lymphocytes produce antibodies (b cells) or cytolysis (cell death) of t cells

Question 20

Platelets

Answer 20

-they are cell fragments that lack nuclei and are involved in clot formation as a response to tissue injury
