What are these species a type of?

Angioplasty is a technique that can reopen narrowed or obstructed arteries in the heart (coronary arteries) without extensive surgery. First performed in 1977, angioplasty is now as common as coronary artery bypass graft surgery.

The treatment of arteriosclerosis is surgical or endovascular if there is a risk of life, significant functional impairment or major risk involving the life of an organ or limb.

Angioplasty is not the only surgery for this, Several surgical techniques aim at restoring the arterial lumen or irrigating the private territory or at suppressing the arterial aneurysm.

- Endoluminal angioplasty or dilation using a balloon with or without a stent to correct a stenosis or to recanalize a short arterial occlusion.

- The removal by endarterectomy which consists of removing the atheroma plug which obstructs an artery leaving only the weed.

- Bridging, which will "short circuit" the obliterated artery by allowing the passage of blood from the healthy artery upstream to the permeable artery downstream, made with venous, arterial or prosthetic material.

In case of an aneurysm two techniques are available: either bypass surgery in conventional surgery removing the aneurysm - or the stent covered excluding the aneurysm.

In all cases the risks must be compared to the benefits of each technique and correctly exposed beforehand. Each act must be adapted to each case according to the functional stage, the general state of the patient and his physiological age more than legal.

What are the three examples to justify Newton first law of motion .

Sergeu [11.5K]

Explanation:

1.Law of Inertia

Inertia : is the ability to resist change in motion.

Example; if you roll a ball it will keep running unless you change it's direction with the help of friction..

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

unbalanced force is a type of force where total force≠zero, means the object will move..

Example; if you will try to push a truck will be less but if you push a car the acceleration will be more.. because car has less mass..

3. the third law of motion state that foreign every action there is a opposite reaction..

Example; can you throw a ball on the floor ...the floor pushes back that the ball..

hope it helps

What are the five functions of the skeleton system

Ann [662]

Protection- the cranium and ribs protect the brain and vital organs in the chest

Shape- gives shape to the body and makes you tall or short

Support- holds your vital organs in place when playing sports. The vertebrae column holds the body upright

Movement- muscles are attached to bones, which are joined. When the muscles contract, the bones move

Blood Production- red blood cells(to carry oxygen) and white blood cells(to protect against infection) are produced in the bone marrow of some bones
