Circulation/respiration

Question 1

Blood composition

Answer 1

The blood is composed of cells, cell fragments and an aqueous solution. Blood makes up about 8% of the human body weight.

Question 2

Blood transfusion

Answer 2

Blood transfusion is generally the process of receiving blood or blood products into one’s circulation intravenously.

Question 3

Heart-anatomy and physiology

Answer 3

1 Nose and nasal passage
2 Larynx 
3 Trachea
4 Bronchi (singular -bronchus)
5 Lungs 
6 Alveoli

Question 4

Pulmonary and systemic circulation

Answer 4

The cardiovascular system is composed of two circulatory paths: Pulmonary circulation, the circuit through the lungs where blood is oxygenated, and systemic circulation, the circuit through the rest of the body to provide oxygenated blood.

Question 5

Comparing arteries, veins and the blood they transport.

Answer 5

Veins are blue blood vessels that carry blood towards the heart. Arteries carry oxygenated blood

Question 6

Major arteries and veins and the blood they transport.

Answer 6

Internal iliac artery: branch of the common iliac artery flowing to the pelvis, the genital organs and inner thigh.

Great saphenous vein: Superficial vein collecting blood from the inner leg and thigh and receiving blood from certain veins of the food; it is the longest vein in the body.

Question 7

EKG reading.

Answer 7

An EKG (electrocardiogram) records electrical activity in the heart. An machine records these electrical signals across multiple heart beats and produces an EKG strip that is interpreted by a healthcare professional.

Question 8

Path of air from atmosphere to the blood.

Answer 8

First, air enters your body either through your nose or mouth. Then when the air is in the nasal cavity, it is humidified, filtered, and warmed. The Pharynx is a pathway in which both air and food travel. After the air has passed through the pharynx, it then proceeds through the larynx where it comes into contact with the glottis, a narrow opening that leads into the trachea. The larynx is also known as your voice box. Air travels through the trachea before it reaches the lungs. The trachea can also be referred to as the windpipe. It attaches to the cartilage located in your throat. From where it then travels downward before it breaks off into two primary bronchi. The bronchi splits into two parts, then bronchial tree, where air passes through the secondary bronchi which enters the lobs within the lungs. These bronchi even more flexible than the primary. After air passes through the secondary bronchi, it then reaches the tertiary bronchi, which are even smaller pathways. After passing through the bronchioles, the air moves into the alveoli, the areas within the lungs where the oxygen is transferred into the blood in exchange for carbon dioxide air is diffused into the blood through a complicated series of chemical reactions.

Question 9

What is gas exchange?

Answer 9

Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs.

Question 10

Mechanism for breathing.

Answer 10

The action of breathing in and out is due to changes of pressure within the thorax, in comparison with the outside.

Question 11

Disorders associated

Answer 11

Influenza - an acute viral infection of the upper or lower respiratory tract that is marked by fever, chills, and a generalized feeling of weakness and pain. In the muscles
