Answer 2

1 CPR Cycle

Question 3

143

Answer 3

Philippine Red Cross Hotline

Question 4

LLF

Answer 4

Look, Listen, Feel

Question 5

is a vital medium for transporting glucose, gases, hormones, and nutrients throughout the human body. It plays an essential role in maintaining homeostasis by regulating pH balance, temperature, and osmotic pressure.

Answer 5

Blood

Question 6

The liquid portion of blood, consisting of:
Water - Forms the majority of plasma.
Proteins - Includes albumins, globulins, and fibrinogen.
Salts - Electrolytes such as sodium and potassium.
Lipids - Fats and other lipid substances.

Answer 6

Plasma

Question 7

Also known as erythrocytes, these cells are responsible for transporting gases. They contain hemoglobin, an iron-containing protein that imparts the red color to blood.

Answer 7

Red Blood Cells (RBCs)

Question 8

Also called leukocytes, these cells are crucial for the immune response and fighting infections.

Answer 8

White Blood Cells (WBCs)

Question 9

These are cellular fragments that play an important role in blood clotting and repairing damaged blood vessels.

Answer 9

Platelets

Question 10

are blood vessels that carry blood away from the heart. They are typically oxygen-rich, although there are exceptions, such as the pulmonary arteries, which transport deoxygenated blood to the lungs. Arteries have thick walls and high elasticity to manage the high pressure of blood pumped from the heart.

Answer 10

Arteries

Question 11

are blood vessels that carry blood to the heart. They usually carry oxygen-poor blood, except for the pulmonary veins, which bring oxygenated blood from the lungs back to the heart. Veins have thinner walls compared to arteries and contain valves to prevent the backflow of blood, aiding in its return to the heart.

Answer 11

Veins

Question 12

are tiny blood vessels where the exchange of oxygen, nutrients, and waste products occurs. At the capillary level, oxygen is delivered to organs and tissues, and carbon dioxide is picked up to be transported away from the tissues. Capillaries have very thin walls to facilitate this exchange.

Answer 12

Capillaries

Question 13

Pumps deoxygenated blood to the lungs for oxygenation.

Answer 13

Right Side

Question 14

Pumps oxygenated blood to the rest of the body.

Answer 14

Left Side

Question 15

Receives deoxygenated blood from the body via the superior and inferior vena cava.

Answer 15

Right Atrium (RA)

Question 16

Pumps deoxygenated blood through the pulmonary artery to the lungs.

Answer 16

Right Ventricle (RV)

Question 17

Receives oxygenated blood from the lungs via the pulmonary veins.

Answer 17

Left Atrium (LA)

Question 18

Pumps oxygenated blood through the aorta to the body.

Answer 18

Left Ventricle (LV)

Question 19

gateways in the heart that ensure unidirectional blood flow and prevent backflow:

Answer 19

Valves

Question 20

Located between the Right Atrium and Right Ventricle.

Answer 20

Tricuspid Valve

Question 21

Located between the Right Ventricle and the pulmonary artery.

Answer 21

Pulmonary Valve

Question 22

Located between the Left Atrium and Left Ventricle.

Answer 22

Mitral (Bicuspid) Valve

Question 23

Located between the Left Ventricle and the aorta.

Answer 23

Aortic Valve

Question 24

Deoxygenated Blood enters the heart through the inferior vena cava (for lower body) and superior vena cava (for upper body) into the Right Atrium.

Answer 24

1st Step in the Pathway of Blood Flow

Question 25

Blood moves from the Right Atrium through the tricuspid valve into the Right Ventricle.

Answer 25

2nd step in the pathway of blood flow

Question 26

The Right Ventricle pumps blood through the pulmonary valve into the pulmonary artery, which carries it to the lungs for oxygenation.

Answer 26

3rd step in the pathway of blood flow

Question 27

Oxygen-rich blood returns to the heart through the pulmonary veins into the Left Atrium.

Answer 27

4th step in the pathway of blood flow

Question 28

Blood moves from the Left Atrium through the mitral valve into the Left Ventricle.

Answer 28

5th step in the pathway of blood flow

Question 29

The Left Ventricle contracts, pushing blood through the aortic valve into the aorta, which distributes oxygenated blood throughout the body.

Answer 29

6th step in the pathway of blood flow

Question 30

The heart requires its own blood supply to deliver oxygen and glucose. This supply comes from:

Answer 30

Coronary Circulation

Question 31

Branch from the aorta and deliver blood to the heart muscle.

Answer 31

Coronary Arteries

Question 32

Carry deoxygenated blood from the heart muscle back to the Right Atrium.

Answer 32

Coronary Veins

Question 33

is the immediate and temporary care given to a person who has suddenly been injured, hurt, or fallen ill.

Answer 33

First Aid
