Peristalsis in the Esophagus event triggers the opening of the gastroesophageal sphincter.

Explanation:

In the esophagus, there are two types of peristalsis occurs.The first one is a "primary peristaltic wave" occurs through which bolus enters esophagus during swallowing.
This "wave pushes the bolus down esophagus", into stomach in a wave lasting about 8–9 seconds.
The esophageal sphincter in the lower region is separated by both sympathetic and parasymphathetic nerves.
The pathways of vagal are a major for the relaxation of reflex of LES and this occurs in LES relaxations.

A 68-year-old female who was admitted with shortness of breath. On your arrival, the patient appears drowsy and is on 10L of oxy

zloy xaker [14]

Answer:

Arterial blood gas (ABG) results from a 68-year-old woman with difficulty breathing show:

Oxygenation (PaO₂): hypoxemia
pH: acidosis
PaCO₂: Hypercapnia
HCO₃⁻: normal

whose interpretation is: respiratory acidosis.

Hypercapnia can produce symptoms such as confusion, drowsiness or lethargy, headache, nausea and vomiting and, in severe states, can cause severe unconsciousness and coma.

Explanation:

Respiratory acidosis is due to a failure in the breathing process that produces hypoventilation, decreasing the partial pressure of oxygen (PaO₂) —hypoxemia— and increasing the partial pressure of CO₂ (PaCO₂), called hypercapnia.

Acidosis is the result of the accumulation of CO₂ in the body, which is reflected as a decrease in pH below 7.35, with no change in bicarbonate content.
Hypoxemia is the decrease of PaO₂ below 60 mmHg.
Hypercapnia is the increase of PaCO₂ in ABG above 45 mmHg.
Normal bicarbonate (HCO₃⁻) values range from 22 to 28 mEq/L in ABG. This compound can be altered in metabolic acidosis.

Hypercapnia mainly affects the nervous system, producing symptoms that alter the state of consciousness of the affected, also producing headache and even nausea and vomiting.

The tubules are the site of sperm production, a process known as ____________ .The stem cells, called ____________ , contain 46

Korvikt [17]

Answer:

Spermatogenesis , Spermatogonia

Explanation:

Gonads are the primary sex organs in the male which are the two testes.

Each testis divide into testicular lobules each 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.

The process is known as spermatogenesis.

This process begins with mitotic division of stem cells which are located close to basement membrane of tubules. The cells are known as spermatogonial stem cells. The division produces two types of cells.

Type A cells are the cells which replenish stem cells and type B cells are the cells which differentiate into spermatocytes. They have number of chromosomes = 46.
