Answer 1

Respiratory volume

1.Volume of air move in and out during quiet breathing - TIDAL VOLUME

In an adult, the tidal volume is about 500 ml.

2. Volume of air that can be forcefully inhaled on top of normal breathing- INSPIRATORY RESERVE VOLUME

It is the volume of air during forced inspiration, that is breathing in air forcefully. It is about 2500 ml to 3500 ml.

3. Increased in emphysema - VITAL CAPACITY

Vital capacity is the total volume of air expired after a maximum inspiration.

This includes the expiratory reserve volume, tidal volume and inspiratory reserve volume.

In Emphysema, the lungs loses their elastic recoil capacity and therefore increases the vital capacity.

4. Largest volume of air that can be moved in and out of the lungs- EXPIRATORY RESERVE VOLUME

It is the the volume of air during forced expiration which is about 1000 ml.

5. Average volume of air would be 500 ml - RESIDUAL VOLUME

It is the volume of air left behind in the lungs after respiratory passage and forced expiration which is about 500-1000 ml.

71. Order from superficial to deep tunica of blood vessels is

ANSWER is A

Tunica externa is the outermost or the superficial part of the blood vessel, lined by smooth muscle wall of tunica media, and the most deep layer is tunica interna having endothelium cells.

72. The one which is not a function of the lymphatic system is

TUNIUA INTERNA TUNI CA MEOIA TUNICA EXTERNA

ANSWER is B

Regulation of calcium ions concentration in the blood

The parathyroid hormone is responsible for the calcium ion concentration which helps in the formation and destruction of bone by remodeling.

Vitamin D is responsible for absorbing calcium.

All the functions of the lymphatic system.

73. Fluid found in the lymphatic vessels is called

ANSWER is D

Lymph

Lymph is a colourless watery fluid which flows through the lymphatic system.

It runs through lymphatic vessels and lymph nodes, which mainly consists of the white blood cells.

74. The vessels that pickup the extracellular fluid from the intercellular space and returned to the circulation

ANSWER is B

Lymphatic vessels

The lymphatic vessels carry the lymph from the peripheral tissues and then transferred to the venous system.

Since, the veins cannot take up the interstitial fluid, the lymph and the lymph vessels help by transferring the blood vessels to the venous system.

75. And accumulation of excess interstitial fluid is called as

ANSWER is C

Edema

Edema is swelling caused due to traped interstitial fluid.

Due to edema, there is an increase in the capillary hydrostatic pressure.

76. Lacteals in the small intestine collect

ANSWER is B

Fats

The lacteral is a lymphatic capillary that helps in absorption of dietary fats through the villi that are present on the small intestine.

77. The main role of macrophages in the lymphatic system

ANSWER is B

Phagocytosis

Macrophages are white blood cells which help in the immune system.

They help in engulfing or eating of the foreign pathogens which is known as phagocytosis.
