Blood

Answer 1

A fluid connective tissue consisting of blood cells, dissolved nutrients and ions suspended in a water liquid

Question 2

Plasma

Answer 2

A yellow, water liquid that is the fluid medium of blood

Question 3

Erythrocytes

Answer 3

AKA red blood cells (RBCs) - disc-shaped cells that contain hemoglobin for the transport of gasses throughout the body, particularly O2 and CO2

Question 4

Leukocytes

Answer 4

AKA white blood cells (WBCs) - a class of lymphocyte that patrols the blood to eliminate pathogens and foreign materials

Question 5

Platelets

Answer 5

Fragments of cells derived from the bone marrow that help facilitate blood clotting

Question 6

Blood vessels

Answer 6

Tubular, muscular orgnas that convey blood through the body

Question 7

Artery

Answer 7

blood vessels with thick, muscular walls that convey blood away from the heart

Question 8

Vein

Answer 8

blood vessels with thinner, muscular walls that convey blood back to the heart

Question 9

Capillaries

Answer 9

Network or small blood vessels within and surrounding organs and tissues where gasses and nutrients are exchanged between the blood and body

Question 10

Heart

Answer 10

A four chambered, muscular pump that forces the movement of blood throughout the entire body

Question 11

Right atrium

Answer 11

The chamber that accepts oxygen depleted blood from the body

Question 12

Tricuspid valve

Answer 12

One-way valve between the chambers of the right side of the heart that prevents back flow from the ventirlce into the atrium

Question 13

Right ventricle

Answer 13

The chamber that accepts oxygen depleted blood from the right atrium, and contracts to force blood into the lungs

Question 14

Pulmonary valve

Answer 14

the one-way valve between teh right ventricle and pulmonary artery; prevents backflow from the artery into the ventricle

Question 15

Left atrium

Answer 15

the chamber that accepts oxygen rich blood from the lungs

Question 16

Mitral valve

Answer 16

One-way valve between the chambers of the left side of the heart that prevents backflow from the ventricle into the atrium

Question 17

Left ventricle

Answer 17

Chamber that accepts oxygen rich blood from the left atrium and forces out to the body via the aorta

Question 18

Aortic valve

Answer 18

the one-way valve between the left ventricle and aorta and prevents back flow between teh aorta and left ventricle

Question 19

Systemic circuit

Answer 19

the blood vessels that convey oxygen rich blood from the heart to all the organ systems and return oxygen depleted blood to the heart

Question 20

Pulmonary circuit

Answer 20

the blood vessels that convey oxygen depleted blood from the heart, through the lungs, and returns oxygen rich blood to the heart

Question 21

Pulmonary artery

Answer 21

A Y or T-shaped artery that exits the top of the right side of the heart that conveys oxygen depleted blood from the heart to the lungs

Question 22

Pulmonary veins

Answer 22

A pair of veins, one on each side, that returns oxygen rich blood from the lungs back to the heart

Question 23

Aorta

Answer 23

The largest artery in terms of diameter and volume that comes straight from the top of the heart and loops down following the spine down to the middle of the pelvic region - all other arteries branch off from the aorta

Question 24

Vena cava

Answer 24

The largest vein in terms of diameter and volume, the vein into which all systemic veins converge to return oxygen depleted blood to the heart

Question 25

Coronary arteries

Answer 25

systemic arteries originating from the aorta tht convey oxygen rich blood to the heart muscle

Question 26

Coronary veins

Answer 26

systemic veins that convey oxygen depleted blood from the heart muscle back to the Superior Vena Cava
