Metals are good conductors of electricity and heat because they have unfilled space in the valence energy band. In the absence of an electric field, conduction electrons travel in all directions at very high velocities. Even at the coldest possible temperature — absolute zero — conduction electrons can still travel at the (the velocity of electrons at the Fermi energy). When an electric field is applied, a slight imbalance develops and mobile electrons flow. Electrons in this band can be accelerated by the field because there are plenty of nearby unfilled states in the band.

1) It supplies nutrition and oxygen to those parts where blood cannot reach.
2) It drains away excess tissue fluids.
3 Lymph returns proteins to the blood from the tissue spaces.
4) Fats from the intestine are also absorbed through the lymph.
5) The lymphocytes and monocytes of lymph act as defensive cells of the body.
6) The lymph also removes bacteria from tissues.

Guarantee - means coverage of entire product. In the event of failure of any of the components/systems of the product - the manufacturer agrees to replace/ repair the faulty product without any additional cost to the customers. Eg. If any software problem or technical glitch is found Apple agrees to replace its iphone, without any additional charges.
Warranty- generally means limited liability for the manufacturer or the supplier of the product.
In this the manufacturer agrees to repair the faulty parts of the product if they happen to fail within a specified time frame or usage duration.

Work done in carrying a charge Q through a potential difference V is given as
Also, Q = I t
Using Ohm's law, V = I R
W = I2 Rt
This work done in carrying the charge th rough the wire appears as the heat produced. i.e.,
H = V I t = I2Rt.
this energy is dissipated as heat energy.
This relationship is also known as Joule's Law of Heating

The heart is an organ that pumps blood throughout the body. It comprises four chambers:
- Atria (upper chambers)
- Ventricles (lower chambers)

The right atrium receives blood from the upper and lower body through the superior vena cava and the inferior vena cava, respectively, and from the heart muscle itself through the coronary sinus. The right atrium is the larger of the two atria, having very thin walls. The right atrium opens into the right ventricle through the right atrioventricular valve(tricuspid), which only allows the blood to flow from the atria into the ventricle, but not in the reverse direction.
The right ventricle pumps the blood to the lungs to be reoxygenated.
The left atrium receives blood from the lungs via the four pulmonary veins. It is smaller than the right atrium but has thicker walls. The valve between the left atrium and the left ventricle, the left atrioventricular valve(bicuspid), is smaller than the tricuspid. It opens into the left ventricle and again is a one-way valve.
The left ventricle pumps the blood throughout the body through the aorta, which is the largest artery in the body. The walls of the left ventricle are the thickest among all the chambers.

The Auricles are smaller and placed above the ventricles. Auricles are partitioned by a muscular called septum.

Respiratory system in human beings:
The respiratory system in human beings consists of the nose, pharynx, larynx, trachea, bronchi and lungs.
- Air is taken in through the nostrils.
- Nostrils further continue into the nasal cavity.
- There is a bony plate called the palate, which separates the oral cavity from the nasal cavity.
- Nasal cavity opens into the pharynx.
- The pharynx is a muscular chamber acting as a common passage for the windpipe or trachea and the food pipe or oesophagus.
- It is connected to the larynx through a slit-like opening called the glottis.
- The larynx connects the pharynx to the trachea.
- The trachea shows the presence of cartilaginous rings.
- The cartilaginous rings provide flexibility thus, facilitating continuous air flow.
- The inner wall of the trachea is lined by a mucous membrane consisting of ciliated columnar epithelium.
- The trachea divides into two branches or tubes called bronchi, one of which enters the right lung and the other enters the left lung.
- The bronchi have cartilaginous rings for distention.
- Each bronchus divides into fine secondary bronchi. These bronchi further divide into finer tertiary bronchi. In the lungs, each bronchus finally divides into finer and smaller branches called bronchioles.
- The bronchioles further divide to form smaller terminal bronchioles.
- The bronchioles divide repeatedly to form a cluster of tiny air chambers called air sacs or alveoli.
- Alveoli have thin and moist walls which enable gaseous diffusion with blood capillaries.
- The lungs are a pair of spongy and elastic respiratory organs protected by a bony rib cage.
- The base of the lungs rests on the diaphragm.
- Each lung is covered by two membranes. The inner membrane is called the inner or visceral pleura and the outer membrane is called the outer or parietal pleura.
- The diaphragm is a curved, musculo-fibrous sheath which separates the thoracic cavity from the abdominal cavity.
- The diaphragm plays a major role during respiration.

The high pressure causes the liquid part of blood to filter out from glomerulus into the renal tube .Glomerular filtrate consists of water, urea, salts, glucose and other plasma solutes. Blood corpuscles, proteins and other large molecules remain behind in the glomerulus.
