Answer:
The correct answer will be option C- endothelial cells of the endocardium.
Explanation:
The pulmonary capillary bed is the network of capillaries in the lungs- alveolar region mainly where gaseous exchange takes place.
This bed receives blood from the pulmonary arteriole which arises from the pulmonary artery. The blood is pumped to this artery through the right ventricle of the heart. The right ventricle- especially the valves is lined from with the endocardium which lines it and prevents the blood from sticking to the inside of the chamber.
Therefore, the blood pumped from the right ventricle is in contact with the endothelial cells of the endocardium and option C is the correct answer.
An unconscious adult victim is gasping for breath and having difficulty breathing. The scene is safe and help has been called. Next you should use the head tilt chin lift procedure.
An unconscious patient is at risk of blocking their airway and suffocating. The main reason for this occurring is due to the tongue. An unconscious patient loses all their muscular tone, and this includes the tongue! The tongue can fall back and block the airway.
This situation is an emergency – without a supply of oxygen reaching the lungs, the patient will suffocate in a matter of minutes.
In CPR, we use the head-tilt, chin-lift method to open the airway.
How to Perform a Head-tilt Chin-lift :
- Kneel next to the patient’s head
- Place one hand on the patient’s forehead and tilt the head gently backward
- Place two fingers under the bony part of their chin and lift the chin vertically upwards
- Take care not to place any pressure on the soft part of the neck as this could obstruct the airway
If a cervical spine injury is suspected, then the modified jaw thrust would be used in place of "head-tilt, chin-lift". The jaw thrust is a technique used on patients with a suspected spinal injury and is used on a supine patient.

Answer:
testes , testicular lobules , seminiferous
Explanation:
Gonads are the primary sex organs in the male which are the two testes.
Each testis is surrounded by the dense connective tissue capsule called tunica albuginea which is responsible for the thickening on the posterior side and forms mediastinum testis.
From this region, the septa penetrate and divide it into about 250 pyramidal compartments (testicular lobules) . Each lobule is containing the sparse connective tissue with the endocrine interstitial cells that secrets testosterone, and also contains one to four highly convoluted seminiferous tubules which is responsible for sperm production.
