Why platelet not active to clotting blood before we have injury?​

Answers

Answer 1

Answer:

Platelets are not activated before an injury occurs because that activation is inhibited while they are circulating and there is no damage to the vacular wall.

Explanation:

Platelets are responsible for forming a haemostatic stopper, at the end of the blood coagulation process. These blood components have the ability to go to the place where the vessel wall is damaged and clump together to prevent blood from leaking out.

Platelet migration and activation occurs when the vascular wall endothelium is injured. When this happens, some substances are released - such as adrenaline, ADP and thromboxane A2, among others - and promote platelet activation.

However, this process should not occur before an injury occurs, as it can promote the formation of thrombi that can circulate in the blood vessels and block them.

An inhibitory mechanism, dependent on nitric oxide and prostaglandins, prevents platelets from being activated and clumping in the absence of injury.

Compare and contrast the three types of bone fractures use at least four medical terms from the chapter in at least four sentences

Answers

Answer:

A stable fracture is where the broken ends of the bone line up and are barely out of place, such as fractures in the rib cage from a big fall. This type would take weeks to heal. An open, or compound, fracture is where the skin may be pierced by the bone or by a blow that breaks the skin at the time of the fracture. The bone may or may not be visible in the wound. This could happen with a radial fracture where there's a cut or blow in the the smaller bone in the forearm. A transverse fracture has a horizontal fracture line. The term "transverse" means horizontal or cross-wise, the fracture line is perpendicular to the diaphysis of the bone. This type of fracture can be intervertebral such as motorcycle accident victims or sports injuries.

Answers

Answer:

Low context communication is a speaker-oriented style where speakers do not hesitate to offer their opinions and expertise (Self-enhancement style). Interpersonal contact between people in general and between those directly involved in communication is usually superficial.

Hope it is helpful to you

Low-context communication leaves minimal room for inference and is explicitly stated.

Even if the addressee is not familiar with the cultural context, they are likely to understand all the information. On the other side, a lot of information is indicated rather than stated in high-context communication.

Listeners in low-context cultures must simply understand spoken or written words as they are, as communication takes place through plainly stated and defined words. Generally speaking, low-context cultures include those of Germany, Sweden, and the United States.
