The right answer is false.
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.
Answer:
d. blood moves from the heart into arteries and into smaller vessels and then back into larger vessels as it makes its way back to the heart.
Explanation:
A closed circulatory system is a system in which blood is separated from the interstitial fluid as it circulates in the blood vessels. In a closed circulatory system blood circulates in one direction that is from the heart and then then returns to the heart again after circulating around one of two routes of circulation. A closed circulatory system can be observed in vertebrates, annelids, mollusks.
Answer:
Explain, using the concept of genetic inheritance, how a complex like a mammal acquires it’s physical traits form both its parents?
Using the genetic inheritance, mammals acquire its physical traits from both parents due to phenotypic traits reflected from the dominance gene over the recessive gene. Phenotypic traits are inherited from parents but only appears physically in offspring
Explanation:
B) lung , because an organism is a living thing. Humans , mold , and bacteria live . A lung is an organ in the organ system
