DISORDERS OF THE CIRCULATORY SYSTEM

Biology - Human Health and Diseases

Following are the diseases that can affect the circulatory system:

⑴ Hypertension:

It is the most common disease affecting the heart and blood vessels. A blood pressure of 120/80 mmHg is considered normal. But the increase in blood pressure beyond 140 mmHg (systolic) and 90 mmHg (diastolic) is called high blood pressure (hypertension). A diet full of oily food is known to increase cholesterol levels, causing thickening of the arteries which results in high blood pressure. Tobacco smoking increases the heart rate, contracts blood vessels and raises blood pressure. High blood pressure can harm the heart, brain, kidneys and eyes.

Class 11 - Physics - Mechanical Properties of Solids and Fluids - Important Points to Remember

1. Elasticity: 

It is the property of a material by which it tries to regain its original configuration after the removal of the deforming force applied to it. Example of perfectly elastic solid, quartz, phosphor, bronze.

2. Plasticity:

It is the property of a body by virtue of which it does not regain its original shape and size even after the removal deforming force, is called plasticity.

Q1. What are Transgenic crops?

Answer: Genetically modified crops that contain or express one or more useful foreign genes are called transgenic crops.

Q2. What are transgenic animals? Give an example.

Answer:  Animals manipulated with the foreign gene and have the ability to express it are transgenic animals. e.g. Rosie, a transgenic cow produced milk containing human alpha-lactalbumin.

Q3. What is BT toxin?

Answer: Bt toxin is an intracellular crystalline protein. It exists as an inactive protoxin that once ingested by an insect, gets activated, binds to the surface of midgut epithelial cells. This causes cell swelling and lysis, leading to the death of an insect.
