Answer:
24 hours
Explanation:
Bacterial pink eye is highly contagious and is typically treated with antibiotic eye drops. It can spread to others as soon as symptoms appear, and it remains contagious for as long as symptoms remain, or for about 24 hours after starting a course of antibiotics.
Answer:
The ventricles are the lower chambers of the heart. There are various grooves in the epicardium; these are the sulcuses. The anterior interventricular sulcus is located on the ventral side of the heart and separates the right and left ventricles.
The inflammation here is totally different and is explained below.
<h3><u>Explanation:</u></h3>
As the tissues of foot are cut, the body senses the injury and immediate vasodialation occurs in the region which leads to the outpouring of different exudates in the interstitial tissue. This results in the increased osmolarity of the surrounding tissue which shows inflammed. This condition is painful too, and red in vision.
In the internal organs, the inflammation is mediated by macrophages which secrete different factors in response to external contaminants. These tissues get wrecked by macrophages in response to antigen and is totally different from this type of inflammation.
In the foot tissue, the white blood cells like monocytes and lymphocytes will accumulate in response to toxins that are inside the body. They will start the primary hypersensitivity in the tissue.
Answer with Explanation:
Homeostasis<u> allows an organism to regulate its internal condition in order to adapt to a changing environment.</u> In order to maintain this, the positive and negative feedback mechanisms (loops) remain essential <em>when it comes to physiological processes that are deemed complicated.</em>
<em>Let's talk about the "Negative Feedback Loop."</em>
- The "baroreceptors" are sensors in the blood vessels.
- For example, when the body's temperature changes, the body's initial reaction is to return to its normal level. So, it goes the same way with blood pressure. When the baroreceptors sense an increase or a decrease in blood pressure, it communicates with the hypothalamus by sending a signal. Then, the hypothalamus sends a message to the organs that are responsible for returning the blood pressure to normal level. These organs are the heart, kidneys and blood vessels. So, if a person experiences a "dropping blood pressure," heart stimulation follows (causing an increase heart rate) due to hormonal vessel constriction. This also allows the kidney to retain more water, thereby increasing the blood pressure.
This is how all these elements work together to achieve homeostasis.
