Question 3

• The heart pumps blood throughout the body in blood vessels.
• Blood flow requires both the __________ of the heart and ______ in blood pressure.

How?

Answer 3

pumping action of the heart ; changes in blood pressure

Question 4

mejor functions of cardiovascualr system

transportation

Answer 4

• blood as the transport vehicle
• cariies oxygen, nuntrients, cell wastes, hormones, and other substances vital for body homeostasis to and from the cells
• includes a muscular pump equipped with one-way valves and a system of large and small “plumbing” tubes within which the blood travels
• Heart (the pump); Blood vessels (the plumbing)

Question 5

Heart as the _____

Answer 5

Heart as the pump

Question 6

Blood vessels as the _____.

Answer 6

Blood vessels as the plumbing.

Question 7

What does the RIGHT side of the heart contains?

ano mas lamang, CO2 or O2?

Answer 7

• low in oxygen
• highin carbon dioxide

Question 8

What does the LEFT side of the heart contains?

ano mas lamang, CO2 or O2?

Answer 8

• high in oxygen
• low in carbon dioxide

Question 9

What happens in Pulmonary Circuit?

Answer 9

• heart to lungs, lungs back to heart

Question 10

In depth Pulmonary Circuit

Its Repleneshing circuit

Answer 10

• blood from right side of the heart is low oxygen, high CO2
• blood travels to the lungs, picks up O2, dumps CO2
• oxygenated blood returned to the left side of the heart then Systemic Circuit goes on

Question 11

What happens in Systemic Circuit?

Answer 11

• heart to body tissues, body tissues back to heart

Question 12

In depth Systemic Circuit

Its Delivery circuit

Answer 12

• oxygenated blood pumped put of left side of the heart delivered to tissues for metabolic functions
• metabolism uses up oxygen, gives off carbon dioxide waste
• deoxygenated, high CO2 blood returns to the right side of the heart… then Pulmonary Circuit again

Question 13

Heart is made up of what type of tissues and muscle?

Answer 13

• cardiac muscle
• cardiac nervous tissue
• protective epithelial
• connective tissues

Question 14

Why is Heart forms a double-sided pump?

Answer 14
