The Circulatory and Respiratory System

Question 1

heart?

Answer 1

is a muscular organ, about the size of a fist, The heart pumps blood through the blood vessels.

Question 2

blood?

Answer 2

is a body fluid that is constantly circulating

Question 3

function of the blood?

Answer 3

• Blood transports oxygen and nutrients, such as glucose, carbohydrate, protein, and minerals.
• Blood also helps removing waste substances such as carbon dioxide.
• Blood is made of Plasma, Red blood cells- containing hemoglobin, White blood cells and Platelets.

Question 4

Blood vessel?

Answer 4

Blood moves through the blood vessels in three parts:

Arteries, Veins, Capillaries

Question 5

Double circulation?

Answer 5

blood passes through heart twice

Question 6

Diseases of cardiovascular system:

Answer 6

Heart attack, Hypertension, and stroke

Question 7

Pulmonary circuit?

Answer 7

is from the heart to the lungs and back to the heart.

Question 8

Pulmonary circuit is also?

Answer 8

1. Deoxygenated blood (carbon dioxide) transported from the right side of the heart to the lungs.
2. so, remove carbon dioxide then the
   Blood will be oxygenated
3. Oxygenated blood transported to the left side of the heart.

Question 9

Systemic circuit?

Answer 9

is from the heart to the other organs and back to the heart.

Question 10

Systemic circuit is also?

Answer 10

1- Oxygenated blood transported from the left side of the heart to all body organs and tissues.

2. Exchange of nutrients and waste occurred in the capillaries
3. Deoxygenated blood transported to the right side of the heart.

Question 11

parts of the Respiratory system?

Answer 11

Nose, mouth, trachea, bronchi, lungs, and alveoli

Question 12

Alveoli features:

Answer 12

• thin walls, large surface area, moist surface, many bloods capillaries.

Question 13

Alveoli function:

Answer 13

allow air to pass in and out of the body and efficient gas exchange to happen.

Question 14

Diseases of Alveoli:

Answer 14

Asthma, Pneumonia and Cardiovascular diseases.

Question 15

Inhale process (Take oxygen):

Answer 15

• provide the oxygen from air to the lung (alveoli)
• the size of alveoli will expand and fill with air oxygen.
• Oxygen moves from the alveoli into the blood.

The Oxygen will diffuse from the high concertation to low concentration. Then the blood will oxygenate.

Question 16

Exhale process Remove carbon dioxide):

Answer 16

• Remove the carbon dioxide from your (lung (alveoli)
• carbon dioxide moves from the blood through capillary into the alveoli.

Carbon dioxide will diffuse from high concentration in the capillary (deoxygenated blood) and low concentration in the alveoli.
