Human beings always have _______.
Heart
Understanding Essential Human Body Parts
The question asks about something that human beings always possess. This implies an organ or feature that is fundamental to being a living human being and is universally present in healthy individuals throughout their life.
Analyzing the Options Provided
Let's consider each option and whether it is something that every human being always has:
- Eyes: Vision is a crucial sense, and most human beings are born with eyes. However, individuals can be born without eyes (anophthalmia) or lose them due to illness, injury, or genetic conditions. Therefore, eyes are not something human beings always have.
- Nose: The nose is vital for breathing and smell. While almost all humans have a nose, severe birth defects or injuries can result in its absence or significant disfigurement, sometimes requiring prosthetic replacements. Thus, a nose is not something human beings always have in a complete, natural form.
- Hand: Hands are essential for performing many tasks. However, congenital conditions (like amelia or phocomelia) can result in a person being born without hands or with underdeveloped hands. Limbs can also be lost due to accidents or diseases later in life. So, hands are not something human beings always have.
- Heart: The heart is a vital organ responsible for pumping blood, delivering oxygen and nutrients throughout the body, and removing waste. The continuous functioning of the heart is necessary for life. A human being cannot survive without a functioning heart (except for brief periods with artificial support like heart-lung machines or transplants). Therefore, as long as a human being is alive, they must have a heart.
Why the Heart is Always Present for Life
The heart is the central component of the circulatory system. Its rhythmic pumping action is what keeps blood flowing, which is critical for every cell in the body to receive oxygen and nutrients and dispose of waste products. Cessation of heart function leads to the rapid failure of other vital organs and death. Thus, the presence of a beating heart is a defining characteristic of a living human being.
Revision Table: Presence of Human Features
| Feature/Organ | Is it Always Present in a Living Human Being? | Explanation |
|---|---|---|
| Eyes | No | Can be absent congenitally or lost later. |
| Nose | No | Can be absent or severely deformed. |
| Hand | No | Can be absent congenitally or lost later. |
| Heart | Yes | Essential for survival; life ceases without it. |
Additional Information: Essential Human Body Parts
The human body relies on several essential or "vital" organs to sustain life. Besides the heart, these include the brain, lungs, liver, and kidneys. While it is possible to live with reduced function of some of these organs or with artificial support for a limited time, none of the other options listed (eyes, nose, hand) are universally essential for merely being alive in the way the heart is.
This analysis confirms that among the given choices, the heart is the only organ that human beings always have as long as they are alive.
Important Questions from Critical Reasoning
In this question, a passage is given followed by a statement. Read the passage carefully and judge the statement based on the given passage.
Over three lakh birds of different species have arrived in Kashmir valley, according to wildlife warden wetlands of Kashmir, Rouf Zargar. Usually every year, approximately 9 lakh birds migrate to the valley from different cold habitats of the world. Therefore, the valley witnesses new species of birds every year. Birds can go any place depending upon the leading flock. Kashmir is comparatively less cold than their own natural habitat which makes birds to start migrating to the valley in September every year.
The birds can help in increasing tourism in the valley. Shikara owner Bashir Ahmad said, "Since tourism in valley is not gaining its pace in valley after 2016 turmoil, these migratory birds can attract tourist from across the globe, if tourism department can project them in planned way, and advertise at big level, definitely it will help to boost tourism in valley"
Statement:
Birds migrate to Kashmir valley as it is colder compared to their natural habitat.
